As the light catches the marbled pattern within this 15mm emerald round cabochon, it creates an attractive sheen. This unique sheen is created by placing a natural paua shell between a black resin back and a rich green curved resin top. You can add this cabochon to a wide variety of projects, including handmade pendants and hair accessories. Paua shell comes from New Zealand, where its coloring and iridescent properties have made it popular with tourists. Because the shells are natural, each cabochon will have a different pattern.
